Create multiple server.properties as per your need
You can see server.properties file inside your config folder, You are new to kafka and need help to setup/install kafka on your machine, then feel free to go through this link.
Now I would like to create 2 more kafka brokers, so replicating the server.properties twice,
Lets change the configurations in the server.properties files
Configurations to be changed:
- broker.id
- log.dirs
- listeners (basically the port)
Changing the broker.id
Changing the log.dirs path
Changing the listeners port
Start multiple brokers now
Starting broker 0 with server.properties
kafka-server-start.bat ..\..\config\server-1.properties
Starting broker 1 with server-1.properties
kafka-server-start.bat ..\..\config\server-1.properties
Starting broker 2 with server-2.properties
kafka-server-start.bat ..\..\config\server-2.properties
Command to get the running brokers ids from the cluster through zookeeper
zookeeper-shell.bat localhost:2181 ls /brokers/ids
0,1,2 – kafka broker id’s we have configured in the server.properties, server-1.properties and server-2.properties respectively.
Command to get more details about the particular kafka broker
pass: 0/1/2 here
zookeeper-shell.bat localhost:2181 ls /brokers/ids/2
That’s all for now.
Hope you created multiple brokers with this tutorial.
